Planning for your migration

• Most Customers look for a technical migration first To S/4HANA or Suite on HANA

• Out of Scope: HANA Live / Analytics

Simple Finance (i.e. S/4HANA)

• Suite on HANA is the stepping stone to S/4HANA Then perform code changes, activate S/4HANA extensions

• S/4HANA direct migration expected late 2015 N.B. Migrating to SoH is a great first step to S/4HANA!

Project Scope

9

• Cover all Technical Migration activities Upgrade to ECC 6.0 EhP7 (if necessary)

Unicode Conversion (if necessary)

HANA Migration

• Restitution “As fast, faster, or much faster”

ABAP code optimization (some things will be slower)

Technical Scope

ECC EHP 7 Upgrade

ECC to HANA MIgration

Future Projects

ECC on HANA

• Build one Integrated Schedule Weekly goals

• Include all teams above And partners!

Assign ownership

• Agree schedule with all teams Takes time (1-2 weeks)

Aligns with project prep phase

• Build first sandbox immediately Recent production copy

Production sized!

Include integration environment (if possible)

• Include test cycle Unit testing

Integration testing

Performance/Stress testing

Sandboxes & Prototyping

13

• Production-sized hardware Loan hardware

Try & Buy programs

• Use the hardware vendor you plan Plan to keep the hardware

Hardware Options for Sandbox

14

• Business Suite systems often venerable Housekeeping is not always done

A clean system is #1 way to de-risk your project!

• DRAM is expensive! Basis tables alone cost ~150GB of DRAM below

Multiplied by N production sized systems! TB!

• Run HANA sizing guide SAP Note 1736976 (BW)

SAP Note 1793345 (ECC)

Look for Big Basis Tables

SAP Note 706478

• Include in Schedule

Housekeeping

15

• Disk Databases are inexpensive Data Reduction rarely considered

• Top 100 tables usually 90% of DB space Run HANA sizing guide

SAP Note 1736976 (BW)

SAP Note 1793345 (ECC)

• Analyze Top 100 tables Create action plan

PSA, DSO Change Log deletion (BW)

IDOC, Old Functional Areas, Data Archiving (ECC)

• Remember every GB saved is 10-20GB stored!

Data Reduction

16

• Test Management is critical Some customers have a mature strategy

Some do not

• Revise your test management strategy Test Automation

Test Coverage

Test Prioritization

• Reduce your time to complete testing! How long does it take to complete regression test?

Change Management & Test Management

• Make sure you are on the latest latest SP! http://scn.sap.com/community/abap/custom-code-management

• Custom Code Management Tools (CCMT) Custom Code Management Cockpit (CDMC)

Usage & Procedure Logging (UPL)

CloneFinder

• Use these tools in combination with: Testing

Process prioritization by business users

Solution Manager is your friend!

• Complete Sizing Sandbox system is a great way to size accurately

Sizing tools are good alternative

• Consider technical architecture HANA supports database multi-tenancy

Architecting for S/4HANA

• HANA supports system replication Active/Passive Synchronous (HA)

Multi-tier Asynchronous (DR)

SUSE Linux supports automated host failover

• Very low cost to implement As compares to e.g. RAC

Most HANA systems are HA

• Even lower cost options Share QA & DR
